Hawaii Scientific Drilling Project – Core Logs

Abstract

Core-drilling for the first phase of the Hawaii Scientific Drilling Project (HSDP) took place from October 25 to December 10, 1993 at a site just east of downtown Hilo. A total depth of 3,464 feet (1,056 meters) was achieved with a recovery rate of greater than 90%. In parallel with the drilling, a major effort was undertaken to process the core in essentially real-time. This involved washing, marking, boxing, splitting, photographing, logging, and sampling the core. Keeping up with the highly successful drilling turned out to be a monumental task, but the team of dedicated geologists, most of whom were effectively volunteering their time, managed to do it. This volume represents a major achievement made possible by their dedication and hard work.
